Abstract

The invention relates to the technical field of composite rubber materials and in particular relates to a composite rubber material and a preparation method thereof. The composite rubber material provided by the invention comprises the following raw materials in parts by weight: 100 parts of butadiene-acrylonitrile rubber, 3-5 parts of a vulcanizing agent, 2-8 parts of an active agent, 0.5-2 partsof an accelerant, 1-2 parts of an anti-aging agent and 5-10 parts of montmorillonite. A montmorillonite reinforcing filler is added to be matched with the butadiene-acrylonitrile rubber so as to forma nano composite material with an intercalated structure, so that the mechanical property, oil resistance, damping capacity and sound insulation property of the butadiene-acrylonitrile rubber composite material can be effectively improved, and noise reduction requirements of electric reactors are effectively met. The prepared composite rubber material is an excellent-performance oil-resistant damping sound-insulation composite material for inner walls of electric reactor tanks.

Description

technical field [0001] The invention relates to the technical field of rubber composite materials, in particular to a rubber composite material and a preparation method thereof, and further relates to an oil-resistant damping sound-insulating rubber composite material for the inner wall of a reactor oil tank and a preparation method thereof. Background technique [0002] With the continuous increase of power demand, the noise problem of substations is becoming more and more obvious. At present, auxiliary noise control measures are often used for noise control of substations, such as the use of a large number of sound-absorbing materials, sound insulation components, and noise reduction devices to block noise transmission. Approach; In order to effectively block the noise passage, people will also adopt measures such as sound insulation cover and large sound insulation room, but this will bring problems such as poor heat dissipation, high cost, and difficult maintenance.
